An apparatus for removing the sprue from an injection mold, having a cylinder and an associated piston rod, in which the piston rod extends between the two halves of the mold into the runner when the injection mold is closed. Molding material is molded around the forward end of the piston rod during the injection. Upon opening of the mold the sprue fixedly carried by the forward end is removed by movement of the piston rod into the cylinder.
